WEST Ham's want-away winger Trevor Sinclair believes he can be the answer to England's problems on the left.

Sinclair, who yesterday put in a written request for a transfer, is convinced a move away from Upton Park will enhance his international chances.

He said: "It's got nothing to do with what anyone else has said. It's something that I want to do for myself.

"And yes, playing for England on that left side has formed a big part of my thinking."

Finding a naturally left-sided attacking player has been a problem for England boss Sven-Goran Eriksson and his predecessor Kevin Keegan.

Nick Barmby started on the left against Greece on Saturday but was substituted after an ineffective performance and replaced by Emile Heskey, who is a central striker.

Sinclair, who is on the fringes of the national team set-up, thinks he will improve his chances of moving up the pecking order - and a place in England's World Cup squad - by playing for a team chasing a Champions League place rather than fighting a relegation battle.

Sunderland have emerged as the favourites to sign the former Blackpool and QPR man.

He said: "I have enjoyed my time immensely and have established a wonderful relationship with the fans.

"However, I think a fresh challenge as part of a new environment will help my performance level in this incredibly important season."
